引入供应链管理思想提高陆航航材保障水平

随着我军陆军航空兵部队的不断壮大，陆航部队担负任务的多元化，以及现代战争的突发性、高消耗性等特点，航材保障已成为影响陆航部队战斗力的一个重要因素。适时地推进我军陆航航材保障的变革，改进航材管理手段，更新航材管理观念已迫在眉睫。     

Quantal-response equilibrium models of the ultimatum bargaining game

This paper investigates the implications of quantal response equilibrium (QRE) models [McKelvey and Palfrey, 1995, Games Econ. Behav. 10, 6–38; 1998, Exper. Econ. 1, 9–41] in the ultimatum bargaining game. It is shown that, in a normal-form QRE (NQRE), each bargainer's decision depends critically on the anticipated behavior of the other, and there is a NQRE in which the proposer makes any offer between zero and equal split as a strict best response. The application of NQRE to the experimental data [Slonim and Roth, 1998, Econometrica 66, 569–596] suggests that the history dependence observed in the experiment is a result of the strategic interactions between bargainers.

Is the J-Curve Effect Observable for Small North European Economies?

The present study tests for the J-curve for five North European countries—Belgium, Denmark, The Netherlands, Norway, and Sweden—using generalized impulse response functions. The results provide empirical support for the J-curve. Each country has an impulse response function generated from a vector error-correction model that suggests that after a depreciation, there will be a dip in the export-import ratio within the first half-year after the depreciation. The long-run export-import ratio appears to be higher than the low point of this early dip in almost all cases. Also, in most cases, the export-import ratio appears in many periods after the depreciation to be converging from below to a higher long-run equilibrium.     

Equilibrium selection in bargaining models

This paper examines evolutionary equilibrium selection in bargaining models. We show that random best-response and continuous best-response learning dynamics give rise to (different) simple sufficient conditions for identifying outcomes as stochastically stable. This allows us to characterize the implications of these dynamics in simple bargaining games.     

Effective Organisational Response by Corporates to India's Liberalisation and Globalisation

The Indian economy began to liberalise and globalise in earnest beginning in 1991. The principal elements of the economy's structural adjustment that have created a far more competitive and turbulent but also opportunity-rich market environment are described. Based on prior Western and Indian research, a model of effective corporate coping with such a market environment has been developed. The model argues that the greater use of policy frameworks representing entrepreneurial, organic, professional, and participatory styles of management, and mechanisms of uncertainty reduction, differentiation, and integration tend to enhance corporate performance in such an environment, while their absence or low usage depresses it. Four sources of information are utilised to assess the model: published information on how Indian corporates have generally coped with economic liberalisation and globalisation, three corporate case studies, data from a recent study of 139 Indian corporates, and another study of 54 Indian corporates. All four sources broadly converge in their support for the model. Several issues relating to the contingency and strategic choice perspectives, and the generalisability, applicability, acceptability, and the diffusion of policy frameworks and redesign mechanisms are discussed.     

Empirical investigation of investment behaviour in Australia's pastoral region*

Optimal intertemporal investment behaviour of Australian pastoralists is modelled using panel data for the period 1979–1993. Results indicate that quasi‐fixity of inputs of labour, capital, sheep numbers and cattle numbers is characteristic of production in the pastoral region. It takes about two years for labour, four years for capital and a little over two years for both sheep numbers and cattle numbers to adjust towards long‐run optimal levels. Results also indicate that, after accounting for adjustment costs, own‐price product supply and input demand responses are inelastic in both the short and long run.     

Fisher and Inference for Scores

This paper examines the work of Fisher and Bartlett on discriminant analysis, ordinal response regression and correspondence analysis. Placing these methods with canonical correlation analysis in the context of the singular value decomposition of particular matrices, we use explicit models and vector space notation to unify these methods, understand Fisher's approach, understand Bartlett's criticisms of Fisher and relate both to modern thinking. We consider in particular the formulation of certain hypotheses and Fisher's arguments to obtain approximate distributions for tests of these hypotheses (without assuming multivariate normality) and put these in modern notation. Using perturbation techniques pioneered by G.S. Watson, we give an asymptotic justification for Fisher's test for assigned scores and thereby resolve a long standing conflict between Fisher and Bartlett.
